Declare FiniteDuration.toCoarsest to return a FiniteDuration

FiniteDuration.toCoarsest is declared with a return type of Duration
even though it can only ever return a FiniteDuration. Change the
declaration to return a FiniteDuration so that using this method
doesn't require a cast or pattern match on the result in cases where
a FiniteDuration is required.
